Both agricultural liming and enhanced weathering spread crushed rocks on fields and have the potential to remove carbon from the atmosphere. We explore how modifying liming for carbon removal works — and whether markets are the best way to fund it.

We collaborated with [C]Worthy to build a tool that will make it easier to see where a marine carbon removal approach called direct ocean removal is most efficient.

We conducted a stakeholder survey showing broad agreement that independent review of CDR protocols is needed. However, there appear to be diverse views on the desired scope and function of such a review.

Some carbon removal projects also result in avoided emissions. This is good for the climate, but can pose challenges for individual projects that are trying to earn carbon removal credits.

Offsets provide few climate benefits and cost California hundreds of millions of dollars each year. When lawmakers reauthorize the state’s cap and trade program this fall, they should eliminate the use of offsets.
We summarize the ongoing debate around what “counts” as CDR, highlighting the trade-offs of each proposed definition. We suggest an alternative set of questions that can provide a more meaningful guide to making effective CDR investments.
In 2024, wildfires burned a record number of forests participating in California's forest offset program, exposing the danger of relying on forests to slow climate change.
A paper using coupled seaweed growth and technoeconomic models to better understand the potential role of seaweed farming for carbon removal and biomass products.
An ex post analysis shows that credited carbon sequestration in California projects is likely non-additional. These findings illustrate the importance of using dynamic baseline controls to credit carbon.
